this fixes some race condition where the content of the layer wasn't
updated because the size didn't changed and the layer was already marked
as updated. just force an update on reconfig.
Fixes#7989
this is preparation for new backends. currently this is done via the
libmpv API but for future new new VOs not based on libmpv we need these
VOCTRL events.
remove the libmpv observer for the macOS specific options and use a
config cache + change callback for runtime changes. this is also a
preparation for new backends and generalises even more, since libmpv
functions can't and shouldn't be used in usual vo backends. for feature
parity the config cache is used.
move all backend independent code parts in their own folder and files,
to simplify adding new backends. the goal is to only extend one class
and add the backend dependent parts there. usually only the (un)init,
config and related parts need to be implemented per backend. furthermore
all needed windowing and related events are propagated and can be
overwritten. the other backend dependent part is usually the surface for
rendering, for example the opengl oder metal layer.
in the best case a new backend can be added with only a few hundred
lines.
It was possible for sway to get incorrectly sized borders if you resized
the mpv window in a creative manner (e.g. open a video in a non-floating
mode, set window scale to 2, then float it and witness wrong border
sizes). This is possibly a sway bug (Plasma doesn't have these border
issues at least), but there's a reasonable workaround for this.
The reason for the incorrect border size is because it is possible for
mpv to ignore the width/height from the toplevel listener and set its
own size. This new size can differ from what sway/wlroots believes the
size is which is what causes the sever side decorations to be drawn on
incorrect dimensions.
A simple trick is to just explicitly commit the surface after a resize
is performed. This is only done if mpv is not fullscreened or maximized
since we always obey the compositor widths/heights in those cases.
Sending the commit signals the compositor of the new change in the
surface and thus sway/wlroots updates its internal coordinates
appropriately and borders are no longer broken.
The original goal was to simplify all this logic to make it less fragile
and breaky. Unfortunately, that didn't exactly happen and things might
actually be more complicated in some ways (well in other ways it's
simplier). There's a lot of negotiation back and forth between the
client and the compositor regarding sizes. The client (aka mpv) can do a
resize on its own. But also the compositor can request its own resize
(which we should be nice and listen to of course). The older method had
a lot of breakfalls/edgecases that were gradually patched up as time
went on, but that approach is really fragile. This refactor should,
hopefully, be on a more solid foundation.
Don't call any of the xdg toplevel state changing functions
(fullscreen, maximized, etc.) directly. Use the toggle wrapper
functions. These signal that the state was changed which is later
handled in the toplevel listener.
Introduce a new vdparams variable that stores the actual dimensions of
the video. This does create some new (but neccesary) complexity.
wl->vdparams stores what the actual dimensions of the video are
(according to mpv). wl->window_size stores the last size of the window
(so it includes any manual resizes for instance). wl->geometry is the
actual size of the output that gets displayed on the screen.
We've had some serious issues with GNOME in the past, but since then
their compositor has undergone some major internal improvements. The
most severe one [1], random vsync spikes and mistimed frames, can no
longer be reproduced by the original author of the issue. There are some
minor UI-related things (lack of window decorations for instance since
there is no xdg-decoration support), but users don't seem to complain
about that too much and they aren't revelant to playback.
3.38 isn't out quite yet, but that should also fix playback issues when
on a multimonitor setup (the fix is in the master branch at the moment).
In terms of playback, the only real concerning issue is the lack of idle
inhibit so a warning is still displayed. But GNOME has their own
workaround that users can use for that so if anyone happens to complain,
we can just point them to that.

When using presentation time, we have to be sure to update the ust when
no presentation events are received to make sure playback is still
smooth and in sync. Part of the recent presentation time refactor was to
use the presentation discarded event to signal that the window is
hidden. Evidently, this doesn't work the same everywhere for whatever
reason (drivers?? hardware??) and at least one user experienced issues
with playback getting out of sync since (presumably) the discarded event
didn't occur when hiding the window. Instead, let's just go back to the
old way of checking if the last_ust is equal to the ust value of the
last member in the wayland sync queue. Fixes#8010.
The motivation for this change was a segfault caused by e107342 which
has complicated reasons for occuring (i.e. I'm not 100% sure but I think
it is a really weird race). The major part of this commit is moving the
initialization of presentation listener to the frame_callback function.
Calling it in swap_buffers worked fine but in practice it meant a lot of
meaningless function calls if a window was hidden (the presentation
would just be immediately discarded). By calling it in frame_callback,
we ensure the listener is only created when it is possible to receive a
presentation event.
Of course calling the presentation listener in feedback_presented or
feedback_discarded was considered, but ultimately these events are too
slow. Receiving the ust/msc/sbc triplet here and then passing it to mpv
results in higher vsync judder since there is (likely) not enough time
before the next pageflip. By design, the frame callback is meant to give
us as much time as possible before the next repaint so calling it here
is probably optimal.
Additionally, we can make better use of the feedback_discarded event.
The wp_presentation_feedback should not be destroyed here. It will be
taken care of either when we get feedback again or when the player
quits. Instead what we can do is set a bool that tells wayland_sync_swap
to update itself based on mp_time delta. In practice, the result is not
any different than before, but it should be more understandable what is
going on now.
Of course, the segfault mentioned at the beginning is fixed with this as
well.
Nothing major but it's technically possible for the
wp_presentation_feedback struct to still be allocated when quitting the
player. Just destroy it if it exists like all of the other wayland
objects.
In a playlist of videos with different sizes, going to the next video
would not properly resize the window. This actually broke way back in
7170910 (oops), but somehow nobody ever complained. The fix is simple.
If a window isn't maximized, be sure to set the window geometry again.
Just some small changes when creating the xdg_surface. Don't set the
toplevel title (or app id) in create_xdg_surface anymore because it's
entirely pointless. Also make it possible for create_xdg_surface to
return something other than 0 so the error checking is somewhat
meaningful. It's not really clear if these xdg functions can even fail
in the first place (perhaps some weird proxy marshalling crap could
possibly go wrong somehow), but it can't hurt. Note that all app id
stuff has been removed (temporarily) in this commit. See the next commit
which adds it back in.
Sway 1.5 started sending more pointer motion events to mpv which broke
the autohiding behavior. The cursor would appear again if you
fullscreened. Sway had a good reason to do this because certain
applications had inconsistencies between hardware cursor and software
cursor without rebasing on state changes[1]. So mpv needs to take this
special case into consideration.
Initially, simply checking mouse coordinates for changes was considered,
but this doesn't work. All coordinates are surface-local in wayland so
something can appear to move in the local coordinate space but not
globally. You're not allowed to know global mouse coordinates in
wayland, and we don't care about local coordinate changes in mpv so this
approach isn't viable.
Instead, let's just keep track of a local state change. If the toplevel
surface changes in some way (fullscreen, maximized, etc.), then just set
a bool that lets us ignore the mp_input_set_mouse_pos function. This
keeps the cursor from appearing simply because the state was changed
(i.e. fullscreening). For compositors that don't send pointer motion
events on a state change, this does technically mean that the initial
mp_input_set_mouse_pos is never set. In practice, this isn't a
noticeable difference though because moving a mouse generates a ton of
motion events so you'll immediately see it on the second motion event.

wl_display_dispatch is dangerous because it will block forever if the
event queue is empty. Any direct calls to this function should just be
replaced with wl_display_dispatch_pending which accomplishes the same
thing for mpv's purposes without any chance of blocking.
The other potential trap is wl_display_roundtrip. It can internally call
wl_display_dispatch which in certain circumstances could potentially
block. There are cases where we need the server to finish processing
client requests before doing anything else so this can not be cleanly
avoided. The dangerous call is the usage of wl_display_roundtrip in
vo_wayland_wait_frame. In the majority of cases, this shouldn't be a
problem because the previous wl_display_read_events should always queue
up some events on the fd for wl_display_roundtrip to send. However, the
compositor could potentially send us an error in the display queue that
could lead to bad behavior when wl_display_roundtrip is called.
The wl_display_roundtrip can't be removed because we are relying on its
semi-blocking capabilities, but the logic can be slightly adjusted to be
safer. The obvious thing to do is to make sure we check the pollfd for
any errors. If one is returned, then we call wl_display_cancel_read and
try again. The less obvious trick is to call wl_display_dispatch_pending
and move wl_display_roundtrip outside of the blocking + timeout loop.
This change has some subtle but important differences. Previously,
vo_wayland_wait_frame would read an event and wait on the server to
process it one-by-one. With this change, the events are dispatched as
soon as possible to the server and then we wait on all of those
(potentially multiple) events to be processed after we have either
received frame callback or the loop times out.
After that is done, we can then check for if there are any errors on the
display. If it's all clear, we can run wl_display_roundtrip without any
worries. If some error happens, then don't execute the function at all.
Previously, the compositor was signaled that a drag-and-drop ended with
wl_data_offer_finish in check_dnd_fd. This is, however, erroneous
because it is outside of the data_device_listener and in some cases
caused errors with certain compositors. check_dnd_fd itself does not
need to know or care about anything that happens in wayland. It just
needs to read data from an fd. The simple fix is to just always signal
the end of a drag-and-drop in data_device_handle_drop. check_dnd_fd can
free memory and close the fd later, but it should not talk to the
compositor. Fixes#7954.
The read of the wayland display fd in vo_wayland_wait_events was
incorrect and technically vulnerable to race conditions. The correct
usage as per the client api is to use wl_display_prepare_read as well as
wl_display_read_events.
Rather than after tone-mapping. This prevents overflow when the
pre-tonemapped signal contains inputs exceeding sig_peak. I also
realized that with this clipping in place, post-clipping no longer needs
to be done, so this isn't even particularly slower.
The only two exceptions to the rule are "clip" and "linear", which
relied on the post-clipping to do their tone mapping properly.
Fixes#7929
This normally gets printed by libplacebo itself when initializing the
context, but due to the way our code is structured (for convenience) we
don't have the log hook enabled by the time this function call is
relevant. So instead just print it manually as an easier work-around
than restructuring the code.
It turns out that the AMD driver doesn't bother to set the size
field in the descriptor for an exported VA surface. I guess they
assume the caller can always use lseek() and don't bother. So, we
need to use lseek() in these situations.
Modified-by: Niklas Haas <git@haasn.xyz>
Guarded this behind PL_API_VER >= 88 to prevent it from exploding on
older libplacebo versions, where vaapi support does not yet work
properly on AMD due to lack of DRM modifiers.
we properly set the unfs window size on live resize end. due to a race
condition in the fullscreen events, which is also a live resize, the
unfs window size is incorrectly set to a fullscreen size. this happens
when the end fs screen event triggers before the end of live resize one.
this just adds a second condition to not be un fullscreen when updating
the unfs window size.
Mess this into the --geometry option, because I like to be
irresponsible. I considered adding a separate option, but at least this
allows me to defer the question how the hell this should work as
property (geometry simply and inherently does not).
Tested on IceWM only. Option equality test and string output not tested.
I'm tired of dealing with this frequent spawning of xdg-screensaver when
debugging and what not. xdg-screensaver was never a serious tool anyway,
it's more like some self-deprecating joke by FDO folks.
This will affect X11 on GNOME and other DEs. I'm singling out GNOME
though, because they are the ones actively sabotaging any sane
technical solutions and community cooperation.
I have been accused of taking it out on innocent GNOME users, while none
of this will reach GNOME developers. Of course that is not the
intention.
This can be used to make vo_libmpv render video to a memory buffer. It
only adds a new backend API that takes memory surfaces. All the render
API (such as frame rendering control and so on) is reused.
I'm not quite convinced of the usefulness of this, and until now I
always resisted providing something like this. It only seems to
facilitate inefficient implementation. But whatever.
Unfortunately, this duplicates the software rendering glue code yet
again (like it exists in vo_x11, vo_wlshm, vo_drm, and probably more).
But in theory, these could reuse this backend in the future, just like
vo_gpu could reuse the render_gl API.
Fixes: #7852
libplacebo exposes this feature already, because this particular type of
bug is unusually common in practice. Simply make use of it, by exposing
it as an option.
Could probably also bump the libplacebo minimum version to get rid of
the #if, but that would break debian oldoldstable or something.
Fixes#7867.
Using mediump float on GLES causes problems with kernel resampling,
PQ HDR, and possibly others. The issues are fixed by using highp,
which is available when GL_FRAGMENT_PRECISION_HIGH is defined.
--dscale= and --*scale-window= (i.e. an empty string) are respectively
valid settings for their options (and, in fact, the defaults).
This fixes the bug that it was impossible to reset e.g. tscale-window
back to the default "unset" setting after setting it once.
Credit goes to @CounterPillow for locating the cause of this bug.
For testing in VMs I guess?
This features a very broken hack that probably works. Though I didn't
test the packed format case. Again, the mismatch is essentially due to
big endian byte addresses decreasing as bit addresses increase, so you
can't represent a bit position in a byte stream with a single address,
which the mpv metadata does.
OSD is broken because repack.c doesn't support big endian. You'll have
to live with it.
For cases in which the requirements of the GPU API prevent directly
uploading a texture with a given stride, we need to fix the stride
manually in host memory. This incurs an extra memcpy, but there's not
much we can do about it. (Even in `ra_gl` land, the driver will just
hide this memcpy from the user)
Note: This code could be done better. It could only copy as many texels
as needed, and it could pick a stride that's a multiple of
`gpu->limits.align_tex_xfer_stride` for better performance. Patches
welcome (tm)

Implementation copy/pasted from:
https://code.videolan.org/videolan/libplacebo/-/commit/f793fc0480f
This brings mpv's tone mapping more in line with industry standard
practices, for a hopefully more consistent result across the board.
Note that we ignore the black point adjustment of the tone mapping
entirely. In theory we could revisit this, if we ever make black point
compensation part of the mpv rendering pipeline.
This standard says we should use a value of 203 nits instead of 100 for
mapping between SDR and HDR.
Code copied from https://code.videolan.org/videolan/libplacebo/-/commit/9d9164773
In particular, that commit also includes a test case to make sure the
implementation doesn't break roundtrips.
Relevant to #4248 and #7357.
glslang accepted this, perhaps erronneously, but mesa does not. It seems
to be incorrect. A caveat is that this means *all* SSBOs are now
coherent, but since we only use SSBOs for peak detection, that's a
non-issue. (And besides, marking something as coherent when we don't
perform any synchronization commands on it should be a no-op anyway)
Fixes#7823
since the title bar catches the mouse up and down events, the underlying
events view doesn't reset the isMoving state and no mouse movements are
signalled to the core. now we also reset the state in mouse up events
on the title bar.
Fixes#7807
The "screenshot window" command (ctrl+s by default) somehow broke video
colors with --gpu-api=vulkan --profile=gpu-hq when playback was paused.
I don't know the cause, but the rest of the code seems to imply
gl_video_reset_surfaces() needs to be called manually to flush some
caches, and it fixes the issue, so I assume there's no great mystery
here.

Commit 6a13954d67 lowered the frequency of wakeups with this
condition. But it seems it sometimes the audio sync mode really should
get the wakeup before the frame is rendered. Normally, vo_thread is
supposed to perform this wakeup. Now the wakeup frequency is twice of
what should be needed - whatever, maybe it can be fixed properly once or
if timing is moved to the VO entirely in the future.
Fixes: #7777 (probably, untested)
When the window is mapped, some ICCCM WM_HINTS are set.
The input field is set to true and state is set to NormalState.
To quote the spec, "The input field is used to communicate to the window
manager the input focus model used by the client" and "[c]lients with
the Passive and Locally Active models should set the input flag to True".
mpv falls under the Passive Input model, since it expects keyboard input,
but only listens for key events on its single, top-level window instead
of subordinate windows (Locally Active) or the root window (Globally
Active).
From the end users prospective, all EWMH/ICCCM compliant WMs (especially
the minimalistic ones) will allow the user to focus mpv, which will allow
mpv to receive key events. If the input field is not set, WMs are
allowed to assume that mpv doesn't require focus.
I'm not sure why it only rendered OSD inside the video. Since OSD
rendering was always done on the X image (after software scaling and
color conversion), there was no technical reason for this. Maybe it was
because the code started out this way, and it was annoying to change it.
Possibly, one reason was that it didn't normally have to clear the black
bars in every frame (if video didn't cover the entire window).
Anyway, simply render OSD to the full window. This gets rid of some
rather weird stuff. It seems to look mostly like vo_wlshm now. The
uncovered regions are cleared every frame, which could probably be
avoided by being clever with the OSD renderer code, but this is where
I'm decidedly losing interest.
There was some mysterious code for aligning the image width to 8 pixels.
Replace that by attempting to align it to SIMD alignment (might matter
for libswscale, or if repack.c gets SIMD). Why are there apparently 4
different ways representing a pixel format (depth, VisualID, Visual,
XVisualInfo), but none of them seem to provide the XImage.bits_per_pixel
value (the actual size of a pixel, including padding)? Even after 33
years, X11 still seems overengineered, confusing, and inconvenient. So
just call X11 a heap of shit, and assume the worst case for alignment.
Make sure to accept only native endian mpv formats. Previously, it
didn't check, and simply matched LE, because these are usually defined
before the BE formats.
red_mask etc. are defined as unsigned long, so use that instead of
hardcoding a 32 bit limit.
Useless, but super generic! Actually may add support for other fringe
formats, however vo_x11 in itself is useless, so nothing won here. Also
I didn't bother with big endian support.
Trying to use anything other than CLOCK_MONOTONIC here would be a
disaster. No idea if it's even possible for the clockid here to be
something other than CLOCK_MONOTONIC in this function but it's better
safe than sorry. Closes#7740.
The image w and h members must match params.w and params.h, so
should not be changed directly. The helper function mp_image_set_size
is designed for this purpose, so just use that instead.
This prevents an assertion error with the rewritten draw_bmp.
Fixes#7721.
Added in libplacebo v60, unfortunately with some changes in design that
make it a bit of an awkward fit for the way timers are used in mpv.
Timer queries in libplacebo don't support "start" and "stop"-style
operations, and instead are attached directly to operations. The only
sane way of implementing this in the ra API is to have a single 'active
timer' that gets attached to every pass, taking care to sort distinct
operations into distinct pl_timer queries within that ra_timer.
This design unfortunately doesn't let us have multiple 'active timers'
concurrently, similar to the current such limitation in ra_gl. But it's
also not a big deal.
Render most of the OSD on the CPU, then draw it using a relatively
simple method. Do this for minimum code maintenance overhead. (While it
doesn't matter for vo_direct3d, and the effort spent here is probably
more than this would ever hope, I do hope to simplify the internal OSD
API for all these fringe VOs. Only vo_gpu should be allowed to do more
sophisticated things.)
If your GPU is shit (which it will be if you "want" to use vo_direct3d),
this might actually improve performance... is what I'd say, but out of
laziness a full screen sized texture gets uploaded on every OSD/subtitle
change, so maybe not.
This isn't useful anymore. We have a much better d3d11 renderer in
vo_gpu. D3D11 is available in all supported Windows versions. The
StretchRect path might still be useful for someone (???), and leaving it
at least evades conflict about users who want to keep using this VO for
inexplicable reasons. (Low power usage might be a justified reason, but
still, no.)
Also fuck the win32 platform, it's a heap of stinky shit. Microsoft is
some sort of psycho clown software company. Granted, maybe still better
than much of the rest of Silly Con Valley.
The original solution for #7017 was sort of a hack, but this hack is no
longer needed because c05e5d9d fixed the underlying issue causing this
error to be spammed in the first place. So just remove the "fix" that
apparently introduced about as many issueas it fixed.
Fixes#7719, hopefully.
This will probably make it slower. But since I don't care about
vo_vaapi, that's perfectly OK. It serves mostly as a test for the
previous commit. In addition, this code was pretty bad (custom broken
scaling and not-blending that probably broke in some situation). If that
wasn't enough, some vaapi drivers also provide only a single overlay at
a time, while this code required a bunch.
There also seems to be a Mesa bug: the overlay gets stretched when
src_x/y was not 0. Or maybe I misunderstood how this is supposed to
work. A bug is probably more likely? Nobody cares about this API.
They are sort of confusing, and they hide the fact that they have an
alpha component. Using the actual formats directly is no problem, sicne
these were useful only for big endian systems, something we can't test
anyway.
This was not intended to be committed in 0e3f893606. It disables
the extra wakeup if working==true. I've convinced myself that the wakeup
was really needed at the time, so no idea how I didn't notice this until
someone pointed it out on the commit diff on github (lol).
This resolves prefixes such as "~/" and "~~/" at the caller, instead of
relying on stream_read_file() to do it. One of the following commits
will remove this from stream_read_file() itself.
Untested.
The caller of render_frame() re-iterates without waiting if this
function returns true. That's normally meant for DS, where we draw
frames as fast as possible to let the driver perform waiting.
This was incorrect at least because the colorspace matrix attempted to
center chroma at (conceptually) 0.5, instead of 0. Also, it tried to
apply the fixed point shift logic for component sizes > 8 bit.
There is no float yuv format in mpv/ffmpeg yet, but see next commit,
which enables zimg to output it. I'm assuming zimg defines this format
such that luma is in range [0,1] and chroma in range [-0.5,0.5], with
the levels flag being ignored. This is consistent with H264/5 Annex E (I
think...), and it sort of seems to look right, so that's it.
Was broken with a zimg wrapper refucktor before the previous commit. In
addition, it seems this didn't match the vo_drm format, or the format
naming convention. So the order actually changes, and the format is
redefined. (The img_format.h comment was probably wrong.)
Change vo_gpu to the new format as well, so we can still test it.
Fallback to drmModeAddFB2 if drmModeAddFB2WithModifiers fails. I've
observed it failing on a pinebook pro running manjaro. We also got "0"
as modifiers from FFmpeg anyway, which might or might not have
something to do with this.
Instead of trying to find the source of the problem, just add this
fallback.
Untested (I don't have a platform that requires modifiers to work
here). Might break something, or might fix something. At least this
looks more intuitive to me.
The current implementation of presentation feedback was designed to be
used with flip model presentation. With the bitblt model,
GetFrameStatistics returns totally different values and it's not clear
if we can use them at all. Previously, this wasn't a problem because
with the bitblt model, GetFrameStatistics only worked in exclusive
fullscreen. Now that mpv supports exclusive fullscreen, we should
explicitly check for a flip model swapchain before using presentation
feedback.
These were still mapped to MP errors during probing, but they also get
triggered when instance creation fails due to lack of support for e.g.
wayland. Since waylandvk is probed above x11vk, we should probably
suppress these by default.
Closes#7626
For some reason this was never done? Looking through the code, it was
never the case that the frame cache was hit for still frames. I have no
idea why not. It makes a lot of sense to do so.
Notably, this massively improves the performance of updating the OSC
when viewing e.g. large still images, or while paused. (Tested on a
4000x8000 image, the OSC now responds smoothly to user input)
This is mostly for testing. It adds passing through the metadata through
the video chain. The metadata can be manipulated with vf_format. Support
for zimg alpha conversion (if built with zimg after it gained alpha
support) is implemented. Support premultiplied input in vo_gpu.
Some things still seem to be buggy.
In the wayland code, the left mouse click is treated a bit differently.
Dragging the left click allows mpv to request a window move to the
compositor. In some cases, this can also request a window resize if the
osc-windowcontrols are enabled. These functions had the strange side
effect of messing up mpv's deadzone (it seemed to disappear completely).
A harmless enough workaround is to just explictly send an UP event for
left click after the move/resize functions are finished executing. The
xdg_toplevel move and resize functions both finish after the button
press is let go, so we are guarenteed to have the left click in the UP
state here. Sending this event probably unconfuses some calculation
somewhere thus fixing the deadzone bug. It feels a little silly, but
it's safe and works. Fixes#7651.
When I added mp_regular_imgfmt, I made the chroma subsampling use the
actual chroma division factor, instead of a shift (log2 of the actual
value). I had some ideas about how this was (probably?) more intuitive
and general. But nothing ever uses non-power of 2 subsampling (except
jpeg in rare cases apparently, because the world is a bad place).
Change the fields back to use shifts and rename them to avoid mistakes.

One not-so-nice hack in the wayland code is the assumption of when a
window is hidden (out of view from the compositor) and an arbitrary
delay for enabling/disabling the usage of presentation time. Since you
do not receive any presentation feedback when a window is hidden on
wayland (a feature or misfeature depending on who you ask), the ust is
updated based on the refresh_nsec statistic gathered from the previous
feedback event.
The flaw with this is that refresh_nsec basically just reports back the
display's refresh rate (1 / refresh_rate * 10^9). It doesn't tell you
how long the vsync interval really was. So as a video is left playing
out of view, the wl->last_queue_display_time becomes increasingly
inaccurate. This led to a vsync spike when bringing the mpv window back
into sight after it was hidden for a period of time. The hack for
working around this is to just wait a while before enabling presentation
time again. The discrepancy between the "bogus"
wl->last_queue_display_time and the actual value you get from the
feedback only happens initially after a switch. If you just discard
those values, you avoid the dramatic vsync spike.
It turns out that there's a smarter way to do this. Just use mp_time_us
deltas. The whole reason for these hacks is because
wl->last_queue_display_time wasn't close enough to how long it would
take for a frame to actually display if it wasn't hidden. Instead, mpv's
internal timer can be used, and the difference between wayland_sync_swap
calls is a close enough proxy for the vsync interval (certainly better
than using the monitor's refresh rate). This avoids the entire conundrum
of massive vsync spikes when bringing the player back into view, and it
means we can get rid of extra crap like wl->hidden.
In theory this mostly happens automatically, especially after the 5
vsync limit disables this already. But if we uninit before 5 vsyncs are
rendered, this can get left in a dangling 'enabled' state, which leaks a
debug report callback.
Always explicitly disable it just to be on the safe side.
In display-sync mode, the core doesn't need to woken up every vsync, but
only every time a new actual video frame needs to be queued. So don't
wake up if there are still frames to repeat.
In audio-sync mode, the wakeup is simply redundant, since there's a
separate timer (in->wakeup_pts) to control when to queue a new frame. I
think.
This finally brings the required playloop iterations down to almost the
number of video frames. (As originally intended, really.)
Also a fairly risky change.
The wakeup at the end of VO frame rendering seems redundant, because
after rendering almost no state changes. The player core can queue a new
frame once frame rendering begins, and there's a separate wakeup for
this. The only thing that actually changes is in->rendering. The only
thing that seems to depend on it and can trigger a wakeup is the
vo_still_displaying() function. Change it so that it needs an explicit
call to a new API function, so we can avoid wakeups in the common case.
The vo_still_displaying() code is mostly just moved around due to
locking and for avoiding forward declarations.
Also a somewhat risky change (tasty new bugs).
Add an infrastructure for collecting performance-related data, use it in
some places. Add rendering of them to stats.lua.
There were two main goals: minimal impact on the normal code and normal
playback. So all these stats_* function calls either happen only during
initialization, or return immediately if no stats collection is going
on. That's why it does this lazily adding of stats entries etc. (a first
iteration made each stats entry an API thing, instead of just a single
stats_ctx, but I thought that was getting too intrusive in the "normal"
code, even if everything gets worse inside of stats.c).
You could get most of this information from various profilers (including
the extremely primitive --dump-stats thing in mpv), but this makes it
easier to see the most important information at once (at least in
theory), partially because we know best about the context of various
things.
Not very happy with this. It's all pretty primitive and dumb. At this
point I just wanted to get over with it, without necessarily having to
revisit it later, but with having my stupid statistics.
Somehow the code feels terrible. There are a lot of meh decisions in
there that could be better or worse (but mostly could be better), and it
just sucks but it's also trivial and uninteresting and does the job. I
guess I hate programming. It's so tedious and the result is always shit.
Anyway, enjoy.
Until now, it used only coordinates clipped to the screen for this,
which meant no negative margins were ever reported to libass. This broke
proper rendering of explicitly positioned ASS events (libass simply
could not know the real video size in this case.)
Fix this by reporting margins even if they're negative. This makes it
apparently work correctly with vo_gpu at least.
Note that I'm not really sure if anything in the rendering chain
required non-negative margins. If so, and that code implicitly assumed
it, I suppose crashes and such are possible.
Change all OPT_* macros such that they don't define the entire m_option
initializer, and instead expand only to a part of it, which sets certain
fields. This requires changing almost every option declaration, because
they all use these macros. A declaration now always starts with
{"name", ...
followed by designated initializers only (possibly wrapped in macros).
The OPT_* macros now initialize the .offset and .type fields only,
sometimes also .priv and others.
I think this change makes the option macros less tricky. The old code
had to stuff everything into macro arguments (and attempted to allow
setting arbitrary fields by letting the user pass designated
initializers in the vararg parts). Some of this was made messy due to
C99 and C11 not allowing 0-sized varargs with ',' removal. It's also
possible that this change is pointless, other than cosmetic preferences.
Not too happy about some things. For example, the OPT_CHOICE()
indentation I applied looks a bit ugly.
Much of this change was done with regex search&replace, but some places
required manual editing. In particular, code in "obscure" areas (which I
didn't include in compilation) might be broken now.
In wayland_common.c the author of some option declarations confused the
flags parameter with the default value (though the default value was
also properly set below). I fixed this with this change.
Previously, the vo wasn't always informed if something about the output
changed during playback. For instance, changing a display's refresh rate
during playback would not update mpv's display fps. Fix this by simply
using VO_EVENT_WIN_STATE in output_handle_done which executes whenever
something about the output is changed.
Allow the --window-maximized and --window-minimized flags to actually
work when the player is started. since macOS doesn't like using both at
the same time the minimized state takes precedence over the maximized
state.
Before this commit, option declarations used M_OPT_MIN/M_OPT_MAX (and
some other identifiers based on these) to signal whether an option had
min/max values. Remove these flags, and make it use a range implicitly
on the condition if min<max is true.
This requires care in all cases when only M_OPT_MIN or M_OPT_MAX were
set (instead of both). Generally, the commit replaces all these
instances with using DBL_MAX/DBL_MIN for the "unset" part of the range.
This also happens to fix some cases where you could pass over-large
values to integer options, which were silently truncated, but now cause
an error.
This commit has some higher potential for regressions.
This was mostly unused, and has certain problems. Just get rid of it.
It was still used in CDDA (--cdda-span) and a debug option for OpenGL
(--opengl-check-pattern). Replace both of these with 2 options, where
each sets the start/end values of the former span. Both were
undocumented somehow (normally we require all options to be documented),
so I'm not caring about compatibility, and not bothering to add it to
the API changelog.
We have this cap now thanks to e2976e662, but we don't actually make
sure our FBOs are storable before we blindly attempt using them with
compute shaders.
There's no more need to unconditionally set `storage_dst = true` as long
as we make sure to include an extra condition on the `fbo_format`
selection to prevent users from accidentally enabling
compute-shader-only features with non-storable FBOs, alongside some
other miscellaneous adjustments to eliminate instances of "assumed
storability" from vo_gpu.
This simply makes the "is the destination FBO format bad?" check a tiny
bit less awful, by making sure we prefer storable FBO formats over
non-storable FBO formats. I'd love to make this also conditional on
whether or not we actually *need* a storable FBO format, but that logic
is decided later, in `pass_draw_to_screen`, and I don't want to
replicate the logic.
Fixes#7017.
Previously if the --fs-screen option was set, it would only use the
screen if mpv was launched with --fs and only on startup. During
runtime, the toggle would ignore it. Rework the logic here so that mpv's
fullscreen always uses --fs-screen if it is set. Additionally, cleanup
some unneeded cruft in vo_wayland_reconfig and make find_output more
useful.
This commit fixes a bug where handle for a framebuffer gets double
freed.
It seems to happen that the same prime fd gets two framebuffers.
As the prime fd is the same the resulting prime handle is also the
same.
This means one handle but 2 framebuffers and can lead to the following
chain:
1. The first framebuffer gets deleted the handle gets also freed via
the ioctl.
2. In startup phase not all 4 dumb buffers for overlay drawing
are set up. It can happen that the last dumb buffer gets the
handle we freed above.
3. The second framebuffer gets freed and the handle will be
freed again resulting that the 4's dumb buffer handle is not
backed by a buffer.
4. Drm prime continues to assign handles to its prime fds an
will lead to have this handle which was just freed to
reassign again but to an prime buffer.
5.Now the overlay should be drawn into dumb buffer 4 which
still has the same handle but is backed by the wrong buffer.
This leads to two different behaviors:
- MPV crashes as the drm prime buffers size als calculated
by the decoder output format. The overlay output format
differs and it takes more space. SO the size check
in kernel fails.
- MPV is continuing play. This happens when the decoders
allocates a bigger buffer than needed for the overlay.
For example overlay is Full HD and decoder output is 4k.
This leads to the behavior das the overlay wil be drawn
into the wrong buffer as its a drm prime buffer and results
in a flicker every fourth step.
the actual character that made mpv crash is IDEOGRAPHIC COMMA
(U+3001, UTF-8: E3 80 81, 、) and that only in some specific
circumstances that could be reliably reproduced on my end.
using an NSString instead of the Swift String actually fixes that issues
even though they should technically do the exact same thing. i tested
all the other String initialisers, but they all had had the same issue.
this is kinda only a workaround till i can find a different way of
handling it.
This was changed 6 years ago (444e583b6) and seemed to work fine. But it
does seem to cause issues with IceWM sometimes, while with StaticGravity
the problem is gone. Comparing both gravity values, reading the confused
source code comment, and reading the referenced commit message, I can't
determine what it even does, I just remove it.
Reproduction:
- start mpv in windowed mode, with 2 videos of different size
- switch to second video
- switch window with alt+tab
- switch back to mpv with alt+tab
- window moves to X=0
There's probably a better way to fix this. Please send a patch.
Libav seems rather dead: no release for 2 years, no new git commits in
master for almost a year (with one exception ~6 months ago). From what I
can tell, some developers resigned themselves to the horrifying idea to
post patches to ffmpeg-devel instead, while the rest of the developers
went on to greener pastures.
Libav was a better project than FFmpeg. Unfortunately, FFmpeg won,
because it managed to keep the name and website. Libav was pushed more
and more into obscurity: while there was initially a big push for Libav,
FFmpeg just remained "in place" and visible for most people. FFmpeg was
slowly draining all manpower and energy from Libav. A big part of this
was that FFmpeg stole code from Libav (regular merges of the entire
Libav git tree), making it some sort of Frankenstein mirror of Libav,
think decaying zombie with additional legs ("features") nailed to it.
"Stealing" surely is the wrong word; I'm just aping the language that
some of the FFmpeg members used to use. All that is in the past now, I'm
probably the only person left who is annoyed by this, and with this
commit I'm putting this decade long problem finally to an end. I just
thought I'd express my annoyance about this fucking shitshow one last
time.
The most intrusive change in this commit is the resample filter, which
originally used libavresample. Since the FFmpeg developer refused to
enable libavresample by default for drama reasons, and the API was
slightly different, so the filter used some big preprocessor mess to
make it compatible to libswresample. All that falls away now. The
simplification to the build system is also significant.
Resizing the window while preserving the aspect ratio actually kind of
sucked. The window size could make big dramatic changes which was pretty
unintuitive with respect to where the mouse was actually located.
Instead, let's just do some math to ensure that the window size is
always contained inside the width/height reported by
handle_toplevel_config while preserving the aspect ratio. Fixes#7426.
Fixes#7441. Just set screenrc to be equal to current_output's geometry.
Also remove some pointless/extra variables and print a warning/fallback
to screen 0 if a bad id is passed to --fs-screen.
X11 is in fact beautiful and superior to Wayland. Instead, just state
what the problem is in most cases: software scaling. (We have
accelerated X11 rendering in vo_gpu and others.)
for reasons unknown to me the NSCursor (un)hide functions can be
completely unreliable and the cursor can have an unknown state. this
only happens on some system and wasn't able to reproduce this. it's
probably some dumb race condition that might be possible to work around,
though because of the lack of reproducibility on my end it's hard to
test.
i decided to rework the cursor hiding code yet again and make it a lot
less greedy. the cursor will now always unhide when moved and there
will never be a situation again the cursor can't be unhidden again.
on the other hand there might be edge cases now where the cursor won't
hide immediately and you have to move it slightly to make it disappear
again. this should be an acceptable tradeoff.
Fixes#6886
Wayland uses vo_wayland_wait_frame plus some polling with a timeout for
blocking on vsync. Here are a couple of changes that seem to be
improvements. First, the poll time is always rounded up instead of
truncated. When rendering frames longer than the standard 16.666 ms
timeout, it seems that truncating the poll time slightly early may cause
some vsync jitter spikes. Waiting longer, even if it's too long, appears
to behave better.
The second change is to use wl_display_roundtrip instead of
wl_display_dispatch_pending. wl_display_dispatch_pending dispatches all
events immediately. This is good to avoid blocking, but it's not
guaranteed to wait long enough for all events to be processed on the
display fd. The preceding wl_display_read_events routine ensures that
all events on the display fd are queued. We just need a semi-blocking
routine to dispatch them for the most reliable vsync.
wl_display_roundtrip will dispatch any events for us, but also wait for
a reply from the display server. This makes it ideal for this role. If
the compositor doesn't reply to the client something else is probably
horribly broken and wrong anyway. It's also not a permanently blocking
call like wl_display_dispatch. If there's no frame callback (i.e. the
window is hidden), then it does not dispatch any events and returns
immediately.
There were a couple of erroneous things in the handle_toplevel_config
function. Firstly, looping through the different states was not handled
correctly. Launching a window as maximized (can happen in sway for
example) was always stuck on true and would never be set to false. Fix
this by always checking if XDG_TOPLEVEL_STATE_MAXIMIZED is found or not.
Also do a similar thing for the fullscreen state.
Additionally, there were some issues with resizing windows and
window-scale going back to old sizes. The root of this problem is that
the width and height arguments of handle_toplevel_config aren't actually
guarenteed to be the actual width and height of the surface. There are
times when mpv will set the surface size on its own (like with
window-scale) which will be unknown to the toplevel listener. To
complicate matters, there are times when we do want to use the width and
height arguments (like when resizing with the mouse).
Fix this by checking if the width and height arguments reported by
handle_toplevel_config changed from the previous call of the function.
If the value is different, then we go ahead and use them when setting
mpv's geometry. If not, then we just ignore it.
On some platforms the ZPOS property might exist, but be immutable.
This is at least the case on Intel Sandy Bridge since Linux kernel
5.5.0. Trying to set an immutable property will cause.
drmModeAtomicCommit to fail with -EINVAL.
On other platforms we might want to set ZPOS to tweak the layering of
planes.
To reconcile these two, simply have drm_object_set_property check if a
property is immutable before attempting to add it to the atomic
commit, instead returning an error code (which is, as previously,
ignored in the case of ZPOS as we don't strictly need it)
This originally existed as a hack for weston. In certain scenarios, a
frame taking too long to render would cause vo_wayland_wait_frame to
timeout which would result in a ton of dropped frames. The naive
solution was to just to add a slight delay to the time value. If a
frame took too long, it would likely to fall under the timeout value and
all was well. This was exposed to the user since the default delay
(1000) was completely arbitrary.
However with presentation time, this doesn't appear to be neccesary.
Fresh frames that take longer than the display's refresh rate (16.666 ms
in most cases) behave well in Weston. In the other two main compositors
without presentation time (GNOME and Plasma), they also do not
experience any ill effects. It's better not to overcomplicate things, so
this "feature" can be removed now.
Add support for setting window-minimized and window-maximized in
Windows. The minimized and maximized state can be set independently.
When the window is minimized, the value of window-maximized will
determine whether the window is restored to the maximized state or not.
Changing state is done with ShowWindow(), which has commands that change
the window state and activate it (eg. SW_RESTORE) and commands that
change the window state without activating it (eg. SW_SHOWNOACTIVATE.)
It would be nice if we could use commands that don't activate the
window, so scripts could change the window state in the backrgound
without bringing it to the foreground, but there are some problems with
that. There is no command to maximize a window without activating it, so
SW_MAXIMIZE is used instead. Also, restoring a window from minimize
without activating it seems buggy. On my Windows 10 1909 PC, it always
moves the window to the back of the z-order. SW_RESTORE is used instead
of SW_SHOWNOACTIVATE because of this.
This also changes the way the window is initially shown. Previously, the
window was made visible as a consequence of the SWP_SHOWWINDOW flag in
the first call to SetWindowPos. In order to set the initial minimized or
maximized state of the window, the window is shown with the ShowWindow
function instead, where the ShowWindow command is determined by whether
the window should be initially maximized or minimized.
Even when showing the window normally, we should still call ShowWindow
with the SW_SHOW command instead of using SetWindowPos, since the first
call a process makes to ShowWindow(SW_SHOW) has special behaviour
where it uses the show command in the process' STARTUPINFO instead of
the command passed to the function, which should fix#5724.
Note: While changes to window-minimized while in fullscreen mode should
work as expected, changing window-maximized while in fullscreen does not
work and won't result in the window changing state, even after leaving
fullscreen. For this to work correctly, the fullscreen logic needs to be
changed to apply the new maximized state on leaving fullscreen.
Fixes: #5724Fixes: #7351
it was possible for mouse events to be triggered when the core was
already being shut down. to prevent this properly close and remove the
window and additional remove the reference to MPVHelper object.
this deprecates the old cocoa backend only option and moves it to the
general macos ones. add support for the new option in the cocoa-cb
layer creation and use the new option in the olde cocoa backend.
Fixes#7272
due to the bundle config the icon is set automatically via the bundle
system mechanisms. this also makes it possible to set the icon to a
custom one with the standard macOS copy paste method via the file info
dialogue.
Fixes#6874
As documented on struct mp_hwdec_ctx, hw_imgfmt specifies the hardware
surface wrapper format for which supported_formats is valid. If this was
not set, f_hwtransfer ignored supported_formats, and assumed all formats
were supported.
Allow the --window-maximized and --window-minimized flags to actually
work when the player is started on wayland. If the compositor doesn't
support maximization or minimization, then these options just do
nothing.
Fixes#7345
There was a multitude of issues with cursor handling in wayland and
behavior seemed to vary for strange reasons across compositors and also
bad things were being done in wayland_common. The problem is complicated
and involved fullscreen states being set incorrectly under certain
instances and so on. The best solution is to just remove most of the
extra cruft. In handle_toplevel_config, instead of automatically
assuming is_fullscreen and is_maximized are false, we should use
whatever value is currently set vo_opts which matters when we initially
launch the window.
hwdec_vaapi tries to probe all available surface formats in advance. For
that, we iterate over _all_ profiles in an attempt to collect possible
surface formats. This means we try profiles we normally wouldn't use for
decoding or filtering, and which could be "unrelated" services.
It seems some drivers report at least one profile, for which
vaQueryConfigEntrypoints() fails (because the profile is not supported;
not sure why it lists it, then). So turn the error message into a
verbose message to avoid confusing output.
Fixes: #7347
This shouldn't really matter, but it's probably best to avoid.
vo_wayland_control would execute set_cursor_visibility while wl->pointer
existed but it didn't check if wl->pointer_id existed. So
wl_pointer_set_cursor would be set to a null surface with an id of 0.
Instead, just wait until we have an actual, non-zero pointer id so that
the cursor is set with the correct, actual id and not a fictious 0 id.
This ensures that the pointer isn't set until it enters the wl_surface
which is what we want.
at the time of the initial dpi query the window is not instantiated yet.
we use a proper fallback in that case, eg the target configured screen
or the main screen if none is set.
also change some weird oversight and a small optimisation.
Theoretically possible (and quite unlikely due to the small texture
size). The code was originally written with the assumption that texture
allocations can't fail, and it was never updated out of laziness.
Untested.
It turns out that gnome wayland still has very serious issues that make
it unusable for playback with mpv. Other compositors mostly behave fine
(Plasma is just missing feature but it's not seriously broken), so GNOME
gets the special honor of having a warning printed out. The only
solution for GNOME users at this time of writing is to either use the
Xorg session or use another wayland compositor.
In the distant past, the cuviddec backed copy hwaccel could be
configured directly using lavc options. However, since that time,
we gained support for automatic hw ctx creation which ended up
bypassing the lavc options.
Rather than trying to find a way to pass those options again, a
better idea is to make the 'cuda-decode-device' option, used by
the interop hwaccels, work for the copy hwaccels too.
And that's pretty simple: we have to add a create function that
checks the option and passes it on to ffmpeg.
Note that this does require a slight re-jig to the configuration
flags, as we now have a scenario where we want to build with support
for the cuda copy hwaccels but not the interop ones. So we need
a distinct configuration flag for that combination.
Fixes#7295.
In vaapi 1.1.0 (which confusingly is libva release 2.1.0), they
introduced a new surface export API that is more efficient, and
we've been supporting that and the old API ever since (Feb 2018).
If we drop support for the old API, we can do some fairly nice cleanup
of the code.
Note that the pkgconfig entries are explicitly versioned by the API
version and not the library version. I confirmed the upstream pkgconfig
files.
As we are less and less interested in vpdpau, with nvdec and vaapi
being better choices in general on nvidia and AMD respectively, we
might consider removing direct_mode, where we bypass the vdpau
mixer and work directly with yuv textures. Normally, working with
yuv textures would be great, but vdpau built in an assumption that
all frames are delivered as separate fields, causing us to have
to re-interleave them.
nvidia then introduces a new OpenGL extension that can return the
yuv frames as frames, but we can't just unconditionally switch to
that as we'd want to keep supporting older hardware where the drivers
are no longer getting new features. The end result is that we
wouldn't be able to get rid of the old code paths.
Removing direct_mode means we always use the mixer, and work with
rgba frame textures. There are some theoretical limitations to
this, but in practice they probably don't matter much - unsupported
colourspaces don't matter because without 10bit decoding support,
we can't use them anyway, and apparently we're not doing separate
chroma scaling these days, so scaling the rbga doesn't really lose
anything (and the vdpau hq scaling option remains available).
GCC 9.2 warns about this. It was always a bit sketchy, so get rid of it.
VK_F10 generates WM_SYSKEYDOWN, so it only needs to be handled in the
WM_SYSKEYDOWN case.
in certain circumstances the video was not redrawn even when the size
or the backing scale factor changed. this could lead to a lower
resolution output than intended.
now it redraws the video when screen properties or the window size
changes.
